I have some military (LC-72) brass that I've been reloading since 1974! Most of it has probably been reloaded 20-25 times! I don't "Hot Load" either!
Keep in mind that this is "MILITARY" brass and it is heavier!
Reloading your brass 5 times is usually a very safe measure, on your part! In most cases, you should be able to get more loads, just keep your eye out for pressure signs, split necks, etc!
